How can we change the parameters of the Effect method ?

You can already specify the name of the effect methods you want to use thanks to the show and update Zone parameter.
But the jQuery effect method can take additional parameters : options, speed and callback.http://jqueryui.com/demos/effect/
You can specify them by using the customZone mixin, wich takes a JSON parameter. Here is an example of this mixin.

The default jQuery selector will be the client id of the component using the mixin. But if you want to use the mixin with an exiting component
(for example our Tabs component), using a Zone, you can use the mixin with this component. you just have to specify a specific jQuery selector,
thanks to the selector parameter.

Tapestry5-jquery project allows you to choose whether to include or not Prototype (and original tapestry components).

In your AppModule inside contributeApplicationDefaults method,
you just have to set the JQuerySymbolConstants.SUPPRESS_PROTOTYPE to "false" in order to force the use of
default prototype implementation of the Tapestry Core components.
